Dinan High-Performance Fuel Pump Upgrade Kit

The Dinan High-Performance Fuel Pump Upgrade Kit is a precision-engineered racing solution for performance-built engines that have exceeded the fuel delivery capacity of the factory pump. As power output climbs through tuning, forced induction, or other engine modifications, the OEM fuel pump increasingly struggles to maintain consistent flow—especially at low fuel levels and during sustained high-load driving.

Dinan's engineering addresses this limitation directly by significantly enhancing the pump's fuel draw capability, ensuring high-volume, uninterrupted fuel delivery whenever the engine demands it most. All fuel system components are constructed from CNC-machined stainless steel adapters, stainless clamps, and premium automotive-grade submersible fuel hose—materials chosen for their corrosion resistance, precision fitment, and long-term durability under extreme operating conditions.

Key Features:

• Enhanced fuel draw capability eliminates flow restrictions during high-demand, aggressive driving
• Prevents fuel starvation and power loss at low tank levels under heavy load
• Fully compatible with the factory Digital Motor Electronics (DME)—no fault codes or warning lights
• CNC-machined stainless steel construction for precision fitment and lasting corrosion resistance
• Designed for seamless integration with the OEM fuel system—no additional modifications required
• Delivers consistent, uninterrupted power all the way to redline during track events and sustained performance driving
• Available as a modification kit (components to upgrade your existing pump) or as a complete pre-modified pump assembly
